USING TRIPLETS TO EVEN OUT YOUR ROLLS

Do your rolls sound bland? Here's how to use a
crescendo to give your rolls some shape. Instead of playing your
doubles at the one low consistent volume (which is certainly a valid
and musical approach), you can give your rolls a different impact,
by doing the following:

1) Throw down the first note hard
like you normally would2) Immediately drop down to the lowest
(and therefore softest) stick height3) Simultaeneously play
these soft notes at the edge of the drum4) Gradually increase
the stick height throughout the duration of the roll, getting louder
5) Simultaeneously bring the sticks into the centre of the drum (the
centre of the drum is louder than the edge)
